Ring-tailed lemurs (Lemur catta) in the Anja community sanctuary, a very successful small project started with WWF assistance three years ago.Situated in cattle-owning Bara country of Southern Madagascar, the huge inselbergs in the sanctuary are known as 'The Three Sisters'. They are sacred to the Bara people who use the caves high up in their walls as burial sites.Lemurs belong to a group of primates called the prosimians, meaning 'before monkeys'. Everywhere in the world except Madagascar, monkeys replaced them 35 million years ago. Madagascar has outstanding biodiversity; most of its flora and fauna is unique to the island and can be found nowhere else.
